Malaria: New molecule with therapeutic potential
For the first time ever, a molecule able to prevent the invasion of blood cells by parasites of the genus Plasmodium , responsible for malaria, has been identified and described by CNRS scientists, * in collaboration with American and English colleagues. Their findings, which have just been published in Nature Communications, confirm the key role that myosin A-the 'molecular motor' of Plasmodium -plays in their infiltration of human hosts and penetration of their red blood cells, which triggers malarial attacks.

A French-German laboratory for identifying the nature of dark matter
  Dark matter remains a scientific mystery: it makes up 26% of our Universe's total energy density, but has never been observed. The CNRS and German research centres from the Helmholtz Association have joined forces to create the Dark Matter Lab (DMLab), an International Research Laboratory (IRL) focusing on the mysterious substance that is dark matter.

The first prehistoric wind instruments discovered in the Levant
The first prehistoric wind instruments discovered in the Levant
Although the prehistoric site of Eynan-Mallaha in northern Israel has been thoroughly examined since 1955, it still holds some surprises for scientists. Seven prehistoric wind instruments known as flutes, recently identified by a Franco-Israeli team 1 , are the subject of an article published on 9 June in Nature Scientific Reports .

Stomata and starch: the dark side of plant water loss
Leaves lose water through tiny pores called stomata. In most plants, stomata open during the day and close at night. A new study conducted by L'Institut Agro and INRAE, published in The Plant Cell, shows that stomata reopen during the night depending on the level of starch stored in the leaves the previous day.

Immunotherapy for blood cancer: remote destruction of tumor cells demonstrated
Immunotherapy for blood cancer: remote destruction of tumor cells demonstrated
The aim of immunotherapy strategies is to use cells in the patient's own immune system to destroy tumor cells. CAR T cell therapy is an immunotherapy that is effective in treating blood cancer. Around 35,000 people are affected by blood cancer each year in France, with 1.24 million cases worldwide.

A Major Advance in the Genetics and Risk Factors of a Form of Infarction That Mainly Affects Women
A Major Advance in the Genetics and Risk Factors of a Form of Infarction That Mainly Affects Women
Spontaneous coronary artery dissection, more commonly known under the acronym SCAD, is a cause of infarction of which 9 out of 10 of its victims are women in their forties in apparent good health. Still poorly understood, it is often underdiagnosed, which complicates treatment despite the fact that it could represent up to one third of infarction cases in women under 60 years of age.

A marine worm, life saver
A marine worm, life saver
In 2020, in the midst of the COVID-19 crisis, we spoke with Franck Zal, a doctor in marine biology from Sorbonne University and founder of the company Hemarina. At the time, HEMO2life - their flagship product created from the hemoglobin of the marine worm, the arenicole - was envisaged to improve the oxygenation of patients suffering from acute respiratory distress syndrome.

Liver cells control our biological clock
Liver cells control our biological clock
The liver could influence the body's central biological clock, a group of brain cells that influence most aspects of physiology and behaviour. Our liver plays a role in regulating our central biological clock, scientists from CNRS and Université Paris have discovered. The results of their study, published on 17 May in Science Advances, show that the biological clock of mice can be reprogrammed by inserting human liver cells into the animal's liver.

Liver cells control our biological clock
Liver cells control our biological clock
The liver may influence the body's central biological clock, a group of brain cells that influence most physiological and behavioral aspects. Our liver partly controls our central biological clock, according to scientists from CNRS and Université Paris Cité. Their study, to be published on May 17, 2023 in the journal Science Advances, has indeed shown that it was possible to shift the biological clock of mice by introducing human liver cells into their liver.

Women and Parkinson’s Disease: Physical Activity Found to Be Beneficial More Than Twenty Years Before Diagnosis
Although physical activity is regularly discussed as being one of the avenues for preventing Parkinson's disease (PD), studies so far had been unable to eliminate certain biases or had not focused on its specific role in women. Researchers from Inserm, Université Paris-Saclay and Université de Versailles Saint-Quentin-en-Yvelines (UVSQ) with the Gustave Roussy Institute studied the impact of physical activity on the development of PD in nearly 100,000 women from the French cohort E3N followed up over 29 years.

New molecule to target and eradicate cancer cells with light
New molecule to target and eradicate cancer cells with light
Scientists have designed a molecule that can accumulate in cancer cells specifically and become toxic upon exposure to light. Scientists from the CNRS, ENS de Lyon, University of Angers, and Claude Bernard Lyon 1 University, in collaboration with colleagues from Swedish and South Korean institutions, have developed a new molecule that selectively accumulates in cancer cells and, after exposure to light, turns toxic.

Eating Broccoli to Limit Skin Allergies
Eating Broccoli to Limit Skin Allergies
The severity of skin allergies can vary depending on many environmental factors, including diet. However, the role of specific nutrients had not been well documented until now. In a new study, researchers from Inserm and Institut Curie at the Immunity and Cancer unit have shown that the absence in the diet of compounds found in certain vegetables, particularly broccoli and cabbage, could worsen skin allergies in animal models.

Agricultural intensification is driving a decline in bird populations across Europe
Agricultural intensification is driving a decline in bird populations across Europe
  Bird populations across continental Europe have declined by 25% in 40 years, with this figure reaching nearly 60% for species found in agricultural environments. Intensive farming is the main source of pressure linked to declining bird populations. These findings come from the largest and most comprehensive bird study to date in Europe.

Health Outcomes of the Nuclear Tests in French Polynesia
The health outcomes of the nuclear tests performed in French Polynesia in the 1970s have been the subject of epidemiological studies at Inserm for several years. Previous research published by a team from Inserm and Université Paris-Saclay with the Gustave-Roussy Institute had studied the relationship between the frequency of thyroid cancer in French Polynesia and the atmospheric nuclear tests performed by France.

James Webb Space Telescope reveals composition of protoplanetary disc
  Young stars are surrounded by discs of material from which future planets form. The James Webb Space Telescope has revealed the chemical composition of the disc around the star J160532, which turns out to be rich in hydrocarbons. In recent years, observations  have shown that rocky exoplanets are very abundant around low-mass stars such as J160532.

Parking problems seen from the standpoint of physics
Parking problems seen from the standpoint of physics
In major metropolises, drivers looking for parking often represent more than 10% of urban traffic 1 , making both pollution and frustration worse! Can physics help understand the headache of parking in cities? Yes, if we are to believe the research conducted by a team led by a CNRS researcher at the Institute of Light and Matter (CNRS/Université Claude Bernard Lyon 1), which has proposed a new approach to the topic.
